1646355-34-1 Usage
Uses
Used in Pharmaceutical Industry:
Linagliptin Impurity H is used as a target for monitoring and control in the production of linagliptin formulations. Its presence is detected and quantified using analytical methods such as high-performance liquid chromatography (HPLC) and mass spectrometry to ensure the quality and purity of the medication for patients. This is crucial for maintaining the safety and efficacy of the diabetes medication linagliptin.
Check Digit Verification of cas no
The CAS Registry Mumber 1646355-34-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,6,3,5 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1646355-34:
(9*1)+(8*6)+(7*4)+(6*6)+(5*3)+(4*5)+(3*5)+(2*3)+(1*4)=181
181 % 10 = 1
So 1646355-34-1 is a valid CAS Registry Number.
